Description
Several observables in flavour physics deviate from their Standard-Model
(SM) expectation. The most prominent ones are related to the decay $b\to
s \mu^+ \mu^-$, with a combined statistical significance well above 4
standard deviations. Similarly, branching fractions of $b \to c \tau
\nu$ decays and the direct CP asymmetry in $K\to \pi \pi$ decays exceed
the SM expectation. I'll discuss theoretical interpretations of these
anomalies and highlight which future measurements will help to confirm
or refute these anomalies and clarify the underlying theory.
